Abstract (en)
[origin: EP3516971A1] An atomizer, comprising an atomizer body (50), a suction nozzle assembly (3), an air inlet (2), an atomization sheet (5), a tobacco tar chamber (4), a tobacco tar guide device and an air outflow passage, a tobacco tar separation chamber (19) is provided in the middle of the tobacco tar chamber (4), and an accommodating chamber is provided in the tobacco tar separation chamber (19); the air outflow passage comprises an air duct (12) arranged in the accommodating chamber, a first gap is reserved between the outer wall of the air duct (12) and the inner wall of the accommodating chamber, and the first gap communicates with the air inlet (2) to form a first air inflow passage (9). The tobacco tar guide device comprises atomization cotton (7), which is of a hollow cylindrical structure; a thermal insulation pipe (10) is sleeved on the lower part of the air duct (12), the upper part of the air duct (12) communicates with the suction nozzle assembly (3), the lower part of the air duct (12) is inserted into the hollow chamber of the atomization cotton (7), a second gap is reserved between the lower end of the thermal insulation pipe (10) and the bottom of the hollow chamber of the atomization cotton (7), and the second gap communicates with the first air inflow passage (9). Thus all the air can pass over, at a low level, the contact surface of the atomization cotton (7) and the atomization sheet (5), so that the atomization is more complete, the atomization efficiency is higher, and more smoke is generated. Meanwhile, the tobacco tar transfer rate can be controlled to prevent the atomization cotton from absorbing too much tobacco tar to produce tobacco tar accumulation.
